Absolutely not! Your yard is gorgeous and think how many years it took to achieve this look, for these trees to grow. You are very lucky.

I wouldn't!

I guess I could limb up some of the trees next to the house so I can see out better. There is a bay window in front that is not visible from where the picture was taken standing on the driveway.

Here's the view from the house looking to the right.

The picture is two years old. I need to do a makeover this Fall. Groundcovers are in order as well as some pruning and perhaps move a few things also.

I love gardening!

Botann,
Before reading your own reply to the question, I had a similar thought that the trees in the mid ground, while having been limbed up over time, were perhaps acting more like a full visual stop rather than a framing device. No doubt part of the process as the garden matures, it is nearly impossible to hold the garden in place, and decisions have to be made in the name of control or artistic vision.

Such a different feeling from a mediterranean California landscape, so many more vertical accents and conifers, and so much more seasonality comes into play.

Open places for me are getting harder to come by over the years. Trees grow faster than most people realize. I sure was fooled! Now I have to limb up some trees to give me more room. Some of those 'trees' are dwarf green and gold Hinokis well over 8ft. high. (2 1/2 meters) I never thought I would have to limb them up. I'd hate to cut them down, and moving them would be difficult at best because of their time in one place.
A lot of people remark about our use of conifers here in the Pac.NW. We take them for granted because they are all around us right up to the tree line in the mountains. That's where I get my inspiration is the subalpine regions.
My garden's vague theme is a lush, lower, subalpine environment.

Depends. For me, I like open spaces and appreciate getting more sun for a healthier lawn. Also, it expands the range of shrub varieties I can put in. I also like more sun coming into the windows of my home. Darkness depresses me!

I am in the process of taking out large deciduous trees and putting in evergreens (broadleaf and conifers) that are not as spreading, but medium tall for screening purposes.

The two matching trees in the middle of the photo (behind the two boulders) are a "visual stop" to the front of the house and, therefore, to the rest of the yard.
Having said that, only you can decide if that is really the angle that most people see the house from or if it's the angle you took the photo from.
Other than those two trees, I wouldn't touch anything.
